Answer» cos¯¹ 12/13 + sin¯¹ 3/5 = sin¯¹ 56/65Taking L.H.S. : ⇒ sin¯¹ 5/13 + sin¯¹ 3/5 Using the formula, sin¯¹x + sin¯¹y = sin¯¹ ( x√1-y² + y√1-x² ) ⇒ sin¯¹ ( 5/13 √1-9/25 + 3 √1-25/169)⇒sin¯¹ ( 5/13 × 4/5 + 3/5 × 12/13)⇒sin¯¹ (30 + 36 / 65)⇒ sin¯¹ (56/ 65) please like the solution 👍 ✔️

Answer»

cos¯¹ 12/13 + sin¯¹ 3/5 = sin¯¹ 56/65Taking L.H.S. :

⇒ sin¯¹ 5/13 + sin¯¹ 3/5

Using the formula, sin¯¹x + sin¯¹y = sin¯¹ ( x√1-y² + y√1-x² )

⇒ sin¯¹ ( 5/13 √1-9/25 + 3 √1-25/169)⇒sin¯¹ ( 5/13 × 4/5 + 3/5 × 12/13)⇒sin¯¹ (30 + 36 / 65)⇒ sin¯¹ (56/ 65)
